Call them innovators, entrepreneurs, or good old-fashioned trouble-makers. These 24 disrupters have gone up against the odds as they've rattled old industries and tried to
create new ones.

In 2000, environmentally conscious Silicon Valley engineer Martin Eberhard was shopping for a sports car with low emissions. The search was fruitless, but it led Eberhard to
build the breakthrough Tesla roadster, a $92,000 two-seater that can go from zero to 60 in four seconds, powered entirely by lithium-ion batteries - and it looks sexy.
Production starts this fall; the first cars (380 have been preordered) will start hitting the road by the end of this year. A family-friendly four-door sedan that'll cost half the
price of the roadster is scheduled for production in 2009. --J.L.Y.
